Title
(EN) METHOD AND DEVICE FOR MAKING A COMPOSITE MATERIAL
(FR) PROCEDE ET DISPOSITIF DE FABRICATION D'UN MATERIAU COMPOSITE
Abstract
(EN)
A method for making a composite material by continuously depositing glass yarns on a moving substrate, at least 80 wt % of the yarns being blended yarns consisting of intimately mixed glass filaments and thermoplastic organic material filaments, and the amount of deposited glass being equal to over 40 wt % of the total amount of material deposited in the form of glass yarns and organic material; transferring the combined glass yarns and organic material to a number of areas where they are heated, compressed and cooled, and specifically heated and/or cooled while simultaneously being compressed; and cutting the resulting assembly into plates or winding it onto a revolving drum.
(FR)
L'invention concerne la fabrication d'un produit composite qui consiste à déposer en continu sur un substrat en mouvement des fils de verre dont au moins 80 % en poids d'entre eux sont des fils co-mêlés constitués de filaments de verre et de filaments de matière organique thermoplastique intimement mélangés, la quantité de verre déposée représentant plus de 40 % en poids de la quantité totale de matière déposée sous la forme de fils de verre et de matière organique; à transférer cet ensemble fils de verre-matière organique dans plusieurs zones où ledit ensemble est chauffé, comprimé et refroidi, le chauffage et/ou le refroidissement dudit ensemble étant accompagné simultanément de sa compression; à découper ledit ensemble sous la forme de plaques ou à l'enrouler sur un tambour en rotation.
